However, most pathogenic AeromonasSanarelli, (1991) reported the first isolates, believed to have been made in 1891, and gave the bacterium the name Bacillus hydrophilus fuscus (now Aeromonas hydrophila). However, in 1943, the International Committee of Systematic Bacteriology recognized Stanier as the genus's creator. In 1965, together with the genera Vibrio and Plesiomonas, this genus was added to the family Vibrionaceae. In 1986, Colwell et al. used DNA-DNA hybridization tests Aeromonas established a distinct evolutionary branch, resulting in the Aeromonadaceae family. The species of the genus were separated into the mesophilic group and the psychrophilic group in the middle of the 1970s based on various characteristics (Tanaka et al., 2017).Isolation of Aeromonas Species from Drinking Water in Al- Khums City and The Determination Antibacterial Activity of Some Medicinal Plant Extracts
